How to Install an Under-mount Sink?
As the counterpart to drop-in sink, under-mount sink is also known as under-counter sink. This kind of sink is installed below the counter, resulting in no lip between the sink and the countertop. The installation of the under-mount sink is a key step for your convenient use in the future and it is not as complicated as some people imagine.
1. Prepare the required materials first, including countertop, an under-mount sink, cutting tool, adhesive, lining plate, and a splint.
2. Prepare a counter suitable for the under-mount sinks and cut a hole in the counter. A quartz table is generally used because it is wear-resistant and easy to take care of. The size of the hole should match the size of the sink and the side wall of the hole needs to be polished.
3. Align the under-mount sink with the hole in the counter and support it with brackets. Then make a stone strip lining using the cutting machine. Bond and fix the under-mount sink and counter with the marble glue and the stone lining plate.
4. You can also use the stone as the bottom splint. Dig a hole suitable for the size of the sink on the bottom splint, and glue the sink between the table panel and the bottom splint with marble glue, just like a sandwich.
5. To make the bond between the under-mount sink and the counter more firm, you can use the plate as the top support to support the sink.
6. Install the accessories of the under-mount sink, such as faucet, strainer and drainpipe. Then apply glass glue to the joint.
7. Conduct a test. Turn on the tap and fill the under-mount sink with water. This is a very crucial and necessary step to make sure the sink won’t leak and everything will run normally. If any problems happen with the under-mount sink, you should figure out the solution to make up for them immediately.
